My husband will be attending a conference in Cork in September of this year and I am considering joining him for a few days and would like some suggestions as what to do and see. We most likely will have 4 full days to spend exploring and don't have a clue where to go and what to see. My only 2 thoughts right now are the Waterford factory and I'd love to visit a castle. Any suggetions or itineraries would be greatly appreciated. Thank you!
